How to edit and build a RT model

As an example, commands for the k1imc model running on k1ioo machine is shown. Please change the model names and machine names accordingly.

1. Edit the Simulink RT model file (.mdl) with Matlab.

   $cd /opt/rtcds/userapps/release/imc/k1/models
   $matlab &

   Run /opt/rtcds/userapps/release/cds/k1/models/startup.m on Matlab to add paths. To edit the Library Blocks, single-click on the block and Ctrl-L to edit them. "dcuid" (FEC) should be different for each model, and the list of DCU IDs are kept at DCUIDList page. "specific_cpu" should also be different for each model on a single machine. iop model has specific_cpu=2, so slave models should have specific_cpu>=3.

2. ssh k1boot, and run the following commands to build the RT model.

   $cdscode (or cd /opt/rtcds/kamioka/k1/rtbuild/current)
   $make k1imc
   $make install-k1imc

3. ssh k1ioo, and run the following commands to start the new model.

   $startk1imc

   You have to press BURT button on the GDS screen (e.g. K1IMC_GDS_TP.adl) when its starting.

4. Edit MEDM screens. Auto-generated screens live in /opt/rtcds/kamioka/k1/medm/k1imc. Your original MEDM screens should be saved in /opt/rtcds/userapps/release/imc/k1/medm. To edit MEDM screens, start MEDM with the command

   $medm &

   and open the file (.adl). Press "Execute" button to see the screen on execution.

OBSOLETE INFO BELOW

1. If you do not understand the meaning of modifying a model file, just stop here. Otherwise you may break whole system.

2. When you modified an existing model file (extension: .mdl) using Simlink on Matlab at /opt/rtcds/rtcore/release/src/epics/simLink/, you need to rebuild the model. If you need to change model name or add a new model, see this page.

3. Type

   >rtr

   or

   >cd /opt/rtcds/rtcore/release

   • Each RTS folder under /opt/rtcds/rtscores/tags/advLigoRTS-2.X.X or /opt/rtcds/rtscores/branches/advLigoRTS-2.X.X includes
     • src/epics/simLink/
       • .mdl (RT model) files. Matlab opens these model files.
     • src/epics/simLink/lib/
       • library for RT models with Matlab. Needs to path at the beginning when Matlab open .mdl files.
4. Make it sure you are on RT PC like standalone.

5. Move proper directly by typing 'rtr' or

   >cd /opt/rtcds/rtcore/release

6. Build IOP;

   >make k1x01
   >make install-k1x01

   and build RT model;

   >make k1vex
   >make install-k1vex

   then,

   > killk1vex
   >startk1x01
   >startk1vex

   to start the new model.
